Japanese Patent Application Laid-Open No. 2002-160104

The present invention relates to a printed circuit board processing machine and a punching processing method thereof.

As a printed circuit board processing machine, for example, a single bed in which a plurality of table mounting areas is formed, and a support area of a plurality of cross slides fixed to the bed throughout the table mounting area and corresponding to the table mounting area are formed. One column, at least one table individually movable in the X direction on the bed, at least one cross slide individually supported in the Y direction on the column, and movable in the Z direction on the cross slide There is a printed circuit board machine with a supported spindle unit. Such a printed circuit board processing machine has a configuration in which a plurality of pedestal printed circuit board processing machines are arranged on a single bed, so that processing in a single bed is also possible even when it is fixed or when the bottom surface changes due to a change with time. The adjustment between modules is not necessary and is fixed, thereby making maintenance adjustment easy. Such a device can be applied not only to the production of small quantities of large quantities of articles, but also to the production of large quantities of small articles (Japanese Patent Laid-Open No. 7-314395).

In the case of a printed circuit board processing machine that uses a drill to drill a printed circuit board, etc., when the machining is performed, move the X table and the cross slide to adjust the shaft center of the drill to the center of the machined part, and then lower the spindle unit. A hole is formed in the printed circuit board by a drill rotatably fixed to the unit.

By the way, when the X table is moved, a vibrating force having a magnitude of acceleration applied to the mass of the X table and the members mounted on the X table is generated in the horizontal direction in the printed circuit board processing machine. Since the action point of the vibration force is higher than the floor, the moment force determined by the vibration force and the height of the action point causes the printed circuit board machine to have a natural frequency determined by the rigidity of the floor and the rotational inertia of the printed circuit board machine. Rotational vibration (locking vibration) occurs. The vibration force transmitted from one side of the leveling bolts disposed on both sides of the printed circuit board processor acts in the direction of pushing down the floor, and the vibration force transmitted from the other side pulls the floor with the center of the printed circuit board processor in between. It acts in the direction of raising. As a result, vibrations in the vertical direction occur at the bottom. Therefore, when the X table is moved at a high speed to improve processing efficiency, the vibration of the floor becomes large.

Therefore, the inertial force generating means and the vibration sensor which consist of the support apparatus which supports a weight so that a movement to a horizontal direction and the weight drive apparatus which drive this weight are installed on a bed, a vibration sensor is mounted in a processing apparatus, and a weight drive is carried out. The apparatus has a printed circuit board processor which moves the weight in accordance with the output signal of the vibration sensor so that the output signal of the vibration sensor is reduced. According to this technique, it can be said that the position precision of a process hole was made excellent (Japanese Unexamined-Japanese-Patent No. 2003-181739).

In addition, although not a printed circuit board processing machine, two sliders on which a machining tool is mounted are disposed coaxially and reciprocated in opposite directions, so that the reaction forces generated are canceled each other to suppress the occurrence of noise and vibration. There is a processing machine to improve the processing precision (Japanese Patent Laid-Open No. 2002-160104)

Japanese Unexamined Patent Application Publication No. 7-314395 does not disclose how processing accuracy can be improved, for example, when processing a printed circuit board having the same processing content.

In addition, even when the cross slide is moved, as in the case where the X table is moved, vibrations in the vertical direction occur at the bottom. This increases the overall drill drilling machine.

In addition, in Japanese Patent Laid-Open No. 2002-160104, although the moving directions of the pair of sliders are opposite to each other, nothing is disclosed about the movement control in the X direction of the main shaft supporting the work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printed circuit board processing machine and a punching processing method thereof which can solve the above problems and improve the processing accuracy without increasing the entire drill drilling machine.

It is characterized by including control means for performing drilling by moving in the opposite direction with respect to the other axis moving in the same direction in FIG. 1.

BEST MODE FOR CARRYING OUT THE INVENTION [

Best Mode for Carrying Out the Invention Embodiments of the present invention will now be described by way of specific examples.

1 is an external view of a printed circuit board processing machine to which the present invention is applied, and FIG. 2 is a processing block diagram of an X-axis driving unit of the NC control apparatus 21 according to the present invention.

The bed 10 of the printed circuit board processing machine M is supported on the floor via the leveling bolt 11 and the block member 12. The table 2a on which the printed circuit board 1a is mounted is movable in the front-rear direction X by the linear guide device and the X-axis drive device 3a (not shown). The table 2b on which the printed circuit board 1b is mounted is movable in the front-rear direction X by a linear guide device and an X-axis driving device 31b, which are not shown. The processing contents of the printed circuit board 1a and the printed circuit board 1b are the same, but the printed circuit board 1b is fixed to the table 2b while being rotated 180 degrees with respect to the printed circuit board 1a.

Column 9 is fixed to bed 10. The cross slide 8a is movable in the left-right direction Y by the linear guide apparatus and Y-axis drive apparatus 7a which are not shown in figure. The cross slide 8b is movable in the left-right direction Y by the linear guide apparatus and Y-axis drive apparatus 7b which are not shown in figure.

The spindle 5a for fixing the drill 4a and the Z-axis drive device 6a for moving the spindle 5a in the vertical direction Z are fixed to the cross slide 8a. The spindle 5b which fixed the drill 4b, and the Z-axis drive device 6b which move the spindle 5b to the up-down direction Z are fixed to the cross slide 8b.

The NC control apparatus 21 controls each part of the printed circuit board processing machine M. As shown in FIG.

2 is a processing block diagram of the X-axis driving unit of the NC control device 21 according to the present invention.

The NC control apparatus 21 reads a machining program, analyzes the content, creates an operation position command on the X axis, and transmits the result to the coordinate conversion apparatus 26. The coordinate conversion apparatus 26 creates the position command A and the position command B from the transmitted operation position command, and transmits the position command A to the drive control unit 22a and the position command B to the drive control unit 22b. The drive control device 22a generates a speed command from the position command A and the position response 25a transmitted from the position detector 24a, and outputs it to the servo amplifier 23a. The servo amplifier 23a generates a torque command based on this speed command, drives the motor 3a to operate the table 2a. Similarly, the drive control device 22b generates a speed command from the position command B and the position response 25b transmitted from the position detector 24b, and outputs it to the servo amplifier 23b. The servo amplifier 23b generates a torque command based on this speed command, drives the motor 3b, and operates the table 2b. And the position command B reversed the code | symbol of the target position coordinate of the position command A, and the processing procedure is the same.

The NC control apparatus 21 produces | generates the same position instruction also about the cross slide 8a, 8b and Z-axis drive apparatus 6a, 6b, and controls the movement operation | movement through the drive apparatus of each axis. The above operation is the same also in the conventional case.

Next, the operation of this embodiment will be described.

FIG. 3 is a diagram showing the center positions a1 to a4 and b1 to b4 of holes for processing the printed circuit board 1a and the printed circuit board 1b to be processed, and the processing procedure. FIG. 4 is a diagram showing the speed command time output from the X-axis driving devices 22a and 22b when the machining operation shown in FIG. 3 is performed, and FIG. 5 shows each of the cases where the machining operation shown in FIG. 3 is performed. It is a figure which shows the speed command time output from a Y-axis drive device, The vertical axis | shaft of these figures has shown the speed command value, and the horizontal axis | shaft has shown time.

As shown by the arrows in Fig. 3, with respect to the printed circuit board 1a, the axis of the drill 4a is moved in the order a1 → a2 → a3 → a4, and is positioned at each position of a1, a2, a3, a4. Machine the hole. On the other hand, with respect to the printed circuit board 1b, the axis of the drill 4b is moved in the order of b1 → b2 → b3 → b4, and holes are drilled at the positions of b1, b2, b3, and b4.

Since the punched positions of the printed circuit board 1b are rotated by 180 ° from the punched positions of the printed circuit board 1a, when the processing contents of the printed circuit board 1a and the printed circuit board 1b are the same, The table 2a, the table 2b, the cross slide 8a, and the cross slide 8b respectively move in opposite directions.

That is, as shown in FIG. 4, the table 2a repeats movement and stop by the speed command pattern shown by the solid line in the figure, and the table 2b by the speed command pattern shown by the broken line in the figure. As shown in Fig. 5, the cross slide 8a repeats the movement and the stop according to the speed command pattern indicated by the solid line in the figure, and the cross slide 8b according to the speed command pattern indicated by the broken line in the figure. Then, the spindles 5a and 5b move up and down at the stop, and the holes 4 are drilled in the printed circuit boards 1a and 1b by the drills 4a and 4b.

In this way, when the table 2a moves, the table 2b necessarily performs the same operation in the opposite direction, and when the cross slide 8a moves, the cross slide 8b necessarily performs the same operation in the opposite direction. Therefore, the vibration force in the horizontal direction generated by each operation is canceled (or reduced). Therefore, since the locking vibration does not occur and the floor vibration does not occur in the printed circuit board processing machine, high precision processing can be realized.

In the above-mentioned printed circuit board machine, even if there is only one printed circuit board to be processed and it can be processed only on one table, the other side is operated in the opposite direction in a dummy (that is, without a printed circuit board). By doing so, the locking vibration can be suppressed and high precision processing can be realized.

When there are two tables, a horizontal moment of rotation occurs every time the table moves, and there is a case of causing a shake in the horizontal direction. However, when there are four tables, for example, as shown in FIG. When the tables at both ends and the two tables at the inner side are paired with each other and selected to perform the opposite operation, it is possible to prevent the horizontal moment of rotation that occurs every time the table is moved.

If the table is odd n, the effect of the above embodiment cannot be expected, but since it can be set to 1 / n of the conventional vibration force generated when the n tables are operated simultaneously, similarly to the case where the table is even , The machining precision can be improved.

(Example 2)

In the first embodiment, one of the two printed circuit boards is rotated by 180 ° with respect to the other side and placed on the table. However, when the machining position is close to point symmetry or point symmetry with respect to the center of the XY direction of the printed circuit board, As shown in FIG. 7, the processing steps of the adjacent printed circuit boards are indicated by giving an arrow to the same figure by making the directions of the printed circuit boards 1a and 1b mounted on the tables 2a and 2b the same. May be processed in reverse with each other.

Incidentally, in the first and second embodiments, the case where the plurality of cross slides 8a and 8b are arranged on one side of the column 9 (the front in FIG. 1) has been described, but may be as follows.

(Example 3)

FIG. 8 is a plan view showing the configuration of another printed circuit board processor to which the present invention is applied, and the same description as in FIG.

As shown in the figure, this printed circuit board processing machine adds the tables 2c and 2d and the cross slides 8c and 8d in addition to the tables 2a and 2b and the cross slides 8a and 8b shown in FIG. Equipped.

The table 2c is arranged on the bed 10 so that the table 2a and the table 2d are coaxial with the table 2b, respectively. The tables 2c and 2d are movable in the front-rear (X) direction by the linear guide apparatus and X-axis drive apparatus 3c, 3d which are not shown in figure. Printed circuit boards 1c and 1d are disposed on the tables 2c and 2d, respectively. The printed circuit board 1c is rotated 180 degrees with respect to the printed circuit board 1a (that is, in the same direction as the printed circuit board 1b), and the printed circuit board 1d is rotated with respect to the printed circuit board 1b. In the state rotated 180 degrees (that is, in the same direction as the printed circuit board 1a), they are fixed to the tables 2c and 2d, respectively.

The non-illustrated linear guides of the cross slides 8c and 8d are parallel to the non-illustrated linear guides of the cross slides 8a and 8b, that is, the movement direction is parallel to the cross slides 8a and 8b. And the inside of the column 9 (upper side in FIG. 9 and rear side in FIG. 1). The cross slides 8c and 8d are movable in the left-right direction Y by the Y-axis drive device which is not shown in figure. The spindle which fixed the drill which is not shown in figure, and the Z axis drive device which is not shown which moves a spindle in the up-down direction Z are fixed to the cross slide 8c. The spindle which fixed the drill which is not shown in figure, and the Z axis drive device which is not shown which moves a spindle in the up-down direction Z are fixed to the cross slide 8d.

The NC control apparatus 21 reads a machining program and, in addition to the position instructions of the tables 2a and 2b and the cross slides 8a and 8b, positions of the tables 2c and 2d and the cross slides 8c and 8d. Write the instructions.

Next, the operation of this embodiment will be described.

Fig. 9 is a diagram showing the center positions a1 to a4, b1 to b4, c1 to c4 and d1 to d4 of the holes to be processed on the printed circuit boards 1a to 1d to be processed, and the processing procedure.

As indicated by the arrows in the drawing, with respect to the printed circuit board 1a, the axis of the drill 4a is moved in the order a1 → a2 → a3 → a4, and each position of a1, a2, a3, a4. Machine a hole in the On the other hand, with respect to the printed circuit board 1b, the axis of the drill 4b is moved in the order of b1 → b2 → b3 → b4, and holes are drilled at the positions of b1, b2, b3, and b4. Moreover, the axis of the drill 4c is moved in order of c1-> c2-> c3-> c4, and a hole is machined in each position of c1, c2, c3, and c4. In addition, with respect to the printed circuit board 1d, the axis of the drill 4d is moved in the order of d1 → d2 → d3 → d4, and holes are drilled at respective positions of d1, d2, d3, and d4.

Since each punched position of the printed circuit board 1c is rotated by 180 ° from each punched position of the printed circuit board 1a, when the processing contents of the printed circuit board 1a and the printed circuit board 1c are the same, The table 2a, the table 2c, the cross slide 8a and the cross slide 8c are respectively moved in opposite directions. Further, since each punched position of the printed circuit board 1d is rotated by 180 ° from each punched position of the printed circuit board 1b, the processing contents of the printed circuit board 1b and the printed circuit board 1d are the same. In this case, the table 2b, the table 2d, the cross slide 8b and the cross slide 8d are respectively moved in opposite directions. In this way, when the table 2a moves, the table 2c always performs the same operation in the opposite direction, and when the cross slide 8a moves, the cross slide 8c necessarily performs the same operation in the opposite direction. . In addition, when the table 2b moves, the table 2d always performs the same operation in the opposite direction, and when the cross slide 8b moves, the cross slide 8d does the same operation in the opposite direction. Therefore, the vibration force in the horizontal direction generated by each operation is canceled (or reduced). In addition, the rotation moment applied to the bed 10 by moving the table 2a and the table 2d (by driving reaction force) is applied to the bed 10 by moving the table 2c and the table 2b. Canceled by the rotational moment in the reverse direction. Therefore, even if the tables 2a to 2d are moved, no rotational force is applied to the bed 10. Similarly, the rotational moment applied to the bed 10 (column 9) by moving the cross slide 8a and the cross slide 8c moves the bed 10 by moving the cross slide 8b and the cross slide 8d. Is canceled by the rotational moment in the reverse direction. Therefore, even if the cross slides 8a-8d move, rotational force is not applied to the bed 10.

As a result, the locking vibration does not occur and the floor vibration does not occur in the printed circuit board processing machine, so that high precision processing can be realized.

Since the drive reaction force is determined by the product of the acceleration in the operation determined by the punching pattern and the mass of the movable part, it is preferable to set the mass to be approximately equal to each of the tables 2a to 2d and the cross slides 8a to 8d.

If the guide devices of the tables 2a and 2c and the tables 2b and 2d are made common and the inner tables 2c and 2d are moved forward, for example, a printed circuit The operation becomes easy when mounting and withdrawing a board | substrate.

In this embodiment, an example of four tables and four cross slides is shown. However, the same effect can be obtained if the tables and cross slides are integer multiples of four. In other words, in the case where there are eight or more tables and cross slides, the present embodiment may be arranged in parallel with the Y direction. In particular, when the operator mounts and retrieves the printed circuit board from the same direction, for example, from the sides of the tables 2a and 2b, rather than lengthening the printed circuit board in the depth direction side by side in the X direction, the work area in the depth direction of the operator is not widened. I can operate it.

In any of the above embodiments, a plurality of spindles may be arranged on each of the cross slides 8a to 8d, and a printed circuit board corresponding to the number of spindles may be mounted on the tables 2a to 2d.

In the above embodiment, the case of a processing machine for forming a hole in a printed circuit board with a drill was described, but instead of the drill, a rooter bit or an end mill may be mounted, and a general machine tool having another positioning mechanism. And the structure of this invention can be applied to a manufacturing apparatus.

It is possible to realize high precision processing by reducing the locking vibration of the printed circuit board processing machine and preventing the floor vibration.

Since there is no need for a special vibration removing device for vibration reduction, a high precision printed circuit board machine can be realized at low cost.
